I've got a problem i wanna expose you:
my generic ESP 01 version 2 ESP8266, starts to spark the blue led after client.subscribe() instruction (PubSubClient .h library related instruction). Untill now is the only case I'd found in which it start to spark.
The Esp continue to work but it loose about 60% of client.publish() i perform. I recognise it with MQTTFX in main desktop pc.
My configuration is:
Arduino Uno R3 + ESP8266 ; eeePC with mosquitto installed
performing an
AT+GMR
I have
AT version:1.1.0.0(May 11 2016 18:09:56)
SDK version:1.5.4(baaeaebb)

Maybe you need to know that I've set the baud rate of the esp at 9600 to make it work properly with softwareserial.
Can you help me to understand my problem?
